Buying Guide: What to Look For
- 1
**Calculate Your Wattage Needs:** Sum the wattage of all devices you plan to connect. Choose a UPS with a VA (Volt-Ampere) rating at least 20-25% higher than your total wattage for headroom.
- 2
**Determine Runtime:** How much backup time do you need? Enough to save files and shut down (5-10 mins) or longer for brief outages (15-30 mins)? Higher VA/wattage provides more runtime.
- 3
**Type of UPS:** Standby UPS (most common for home) provides basic protection. Line-interactive (more stable) is good for fluctuating power. Pure sine wave (premium) is best for sensitive electronics.
- 4
**Number and Type of Outlets:** Ensure it has enough battery-backed and surge-only outlets for all your devices. Look for options with coaxial or Ethernet protection if needed.
Frequently Asked Questions
Q:What's the difference between a surge protector and a UPS?
A surge protector shields devices from voltage spikes. A UPS does that AND provides battery backup power, allowing your devices to continue running or be safely shut down during a power outage.
Q:How long will a UPS power my devices?
This depends on the UPS's capacity (VA/wattage) and the power draw of your connected devices. A typical desktop PC with a monitor might get 5-15 minutes from a mid-range UPS, enough for a graceful shutdown.
Q:Do UPS batteries need to be replaced?
Yes, UPS batteries typically last 3-5 years. Many higher-end UPS models offer user-replaceable batteries, extending the lifespan of the unit. You'll usually get an indicator when replacement is needed.
